If the bird in your dream is locked in a cage, then maybe you are like a bird that has lost the right to fly freely and feel trapped. Maybe you are ambitious and difficult to stretch in real life; Or you lose your freedom of action and can't decide your life freely.
When dreaming about birds, pay attention to what birds they are, wild birds or domestic birds. Wild birds are more inclined to your unconstrained primitive nature, while tame birds may be part of your habit of being protected or dependent on others. Different birds represent different qualities of you. For example, the parrot in your dream may symbolize that you always want to imitate others. Pigeons may be your peace-loving part. The eagle may represent your arrogant and unruly personality.
It is worth noting that if the bird in your dream is injured, it is that your inner part is injured! Think about which part, and give treatment in time!
